C++ DLL注入"CreateRemoteThread“返回0

Question

所以我正在编写一个DLL注入程序，使用OpenProcess、VirtualAllocEx、WriteProcessMemory等等。

在我打电话给CreateRemoteThread之前，一切看起来都很顺利。我三次检查了Microsoft文档并查看了几个示例，因此我确信我已经正确地使用了该函数，但是它正在返回0。

这是我的密码：

// path to DLL
LPCSTR dllPath = "C:\\Users\\user\\OneDrive\\Desktop\\dllname.dll";

// process handle
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, 9440);

// dll base address
LPVOID baseAddress = VirtualAllocEx(hProcess, NULL, strlen(dllPath) + 1, MEM_COMMIT, PAGE_READWRITE);

// write to process memory
WriteProcessMemory(hProcess, baseAddress, (LPCVOID) dllPath, strlen(dllPath) + 1, NULL);

// kernel32's LoadLibraryA function
LPVOID loadLibrary = (LPVOID) GetProcAddress(GetModuleHandleA("kernel32.dll"), "LoadLibraryA");

// create remote thread -- This is what returns 0 (not sure why)
HANDLE hLoadThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE) loadLibrary, baseAddress, 0, 0);

// wait to inject
WaitForSingleObject(hLoadThread, INFINITE);

// print debugs
std::cout << "Successfully injected." << std::endl << std::endl;
std::cout << hProcess << std::endl;
std::cout << baseAddress << std::endl;
std::cout << loadLibrary << std::endl;
std::cout << hLoadThread << std::endl;
std::cin.get();

// free memory
VirtualFreeEx(hProcess, baseAddress, strlen(dllPath) + 1, MEM_RELEASE);

下面是控制台的输出：

Successfully injected.

0x110
0x3a9c0000
0x75dd0bd0
0 <-- this is the return value of CreateRemoteThread

我尝试过在参数中设置null/0并删除WaitForSingleObject调用，但都没有给出结果。

任何帮助都将不胜感激。

发现了问题。我使用MingGW 32位进行编译，而不是使用64位，所以我创建了VS解决方案，并将其修复。谢谢你的帮助“退休忍者”。
